A workpiece conveying device includes a traveling platform which moves on traveling rails, a workpiece sucker arranged below the traveling platform, a vertical drive guide which is provided on the traveling platform and vertically drives the workpiece sucker, and a fork which is placed on the workpiece sucker so as to sandwich the workpiece sucker. With this structure, effects are obtained such that the workpiece conveying device is capable of achieving space saving in a factory and is capable of improving moving accuracy and increasing a moving speed while making it difficult to damage a product.

Workpiece conveying device

A laser machining apparatus includes: an optical-scanning laser machining device that includes a machining head, which moves in a first direction and a second direction intersecting the first direction and emits laser light on a workpiece to machine the workpiece; a first marking device that is provided on one side of the optical-scanning laser machining device in the first direction and puts a mark on the workpiece; a second marking device that is provided on another side of the optical-scanning laser machining device in the first direction and puts a mark on the workpiece; and a pallet on which the workpiece to be machined by the optical-scanning laser machining device is loaded and which moves in the first direction between the first marking device and the second marking device.

Laser machining apparatus

A laser processing device including: a laser oscillator; a processing table; a transmission optical system for transmitting laser light emitted from the laser oscillator to the processing table; a processing head for condensing and radiating the laser light transmitted via the transmission optical system to an object to be processed; a moving mechanism for changing a relative position between the object to be processed and the laser light to be radiated to the object to be processed; and a variable curvature spherical mirror. The transmission optical system includes a reflective beam expander mechanism for collimating and magnifying the laser light from the laser oscillator. The reflective beam expander mechanism includes a spherical mirror and a concave mirror having different curvatures in two orthogonal axes.
